A Quality Measurement Model for Class Component

摘要

Class component is a primitive element and an important product in object-oriented software design. The quality of class component not only may implicate the operations of following phases, but also may affect the quality of object-oriented software system. How to control and improve the quality of class component becomes a major issue in object-oriented design. Modularity, complexity and major documents quality are criteria characteristics for measuring the quality of class component. However, each individual software metric cannot measure the overall quality characteristics of the class component. Therefore, the software metrics must be combined, and conflicts among the software metrics must be reduced. In this paper, a rule-based quality measurement model will be proposed. The model is based on dynamically weighted linear combinations and conflicts reducing production rules. Applying this model, a highly flexible and practical metric combination approach can be created, the conflicts among individual primitive metrics can be reduced. Inheriting the class component with high quality, the following phases not only can continue the high quality products, but also can improve the quality of following phases and reduce the development time and cost.
